Abstract

A system and method for communication of radio frequency (RF) signals over multimedia signal paths. The invention provides a wireless multimedia carrier (WMC) system capable of receiving a variety of standardized input signals, such as DS0/E0, T1/E1, T2/E2, and/or T3/E3 for transmission using RF channels. The WMC system selectively employs time division multiple access (TDMA) and/or code division multiple access (CDMA) technology. The WMC system transmits the various signal inputs using RF carriers, receives the transmitted signals, and converts the signals to the desired signaling scheme (standard) for forwarding to intended destinations.
